Default Series 4 rear end carrier?

I bought a used Series 4 rear end carrier(differential), the code is correct for 4:11 gears that year.

BUT! Is there any way to confirm that the gears inside are really 4:11's?

Len,

Rotate the assembly and count the number of revolutions of the input yoke versus the half-shaft yokes.

Many ring and pinion sets have the tooth count stamped on the end of the pinion. For example, 41-9 (9 pinion teeth and 41 on the ring gear)= 4.56 ratio.

9 on the pinion and 37 on the ring.



There were some "red" spots on the pinion and a few on the ring.....whats that from?
